Overview

The Okuma MULTUS B200II is a horizontal multitasking turning and milling center that combines a powerful turning spindle with a true B-axis milling spindle for complete part machining in a single setup. It sits at the compact end of the MULTUS B series, designed for shops that need full multitasking capability without the size and cost of the larger B400II and B750. Maximum turning diameter is 630 mm (24.8 in) with a maximum machining length of 750 mm (29.5 in).

The main turning spindle delivers 22/15 kW (30/20 hp) at up to 5,000 RPM with 300 Nm (221 ft-lb) of torque through an A2-6 spindle nose with 65 mm (2.56 in) bar capacity. The milling spindle runs up to 12,000 RPM with 22/18.5 kW (30/25 hp) through a Capto C6 tooling interface, providing genuine machining center performance for drilling, boring, tapping, and contour milling.

The B-axis swings 225 degrees (-30 to +195 degrees) with 0.001-degree minimum increment, driven by a direct-drive motor for zero-backlash positioning. Combined with C-axis rotation, Y-axis travel of 130 mm (5.1 in), and the standard ATC holding 40 tools (options up to 80), the MULTUS B200II can reach virtually any angle on a workpiece for complex 5-axis-like machining.

X-axis travel is 390 mm (15.4 in) and Z-axis travel is 750 mm (29.5 in). Rapid traverse hits 40 m/min on X and Z. An optional sub-spindle enables back-end machining without unclamping, making the B200II a true done-in-one platform. Okuma's Thermo-Friendly Concept and Collision Avoidance System are standard.

The MULTUS B200II competes with the Mazak Integrex i-200, DMG Mori CTX beta 1250 TC, and Nakamura-Tome MX-100. Pricing runs $350,000-$500,000 new. Machine weight is approximately 12,500 kg (27,558 lb). The machine targets aerospace, medical, and precision job shops that need to consolidate turning, milling, drilling, and contouring into a single chucking.

Strengths & Limitations

Strengths

True B-axis milling spindle with 225-degree swing and Capto C6 interface provides genuine machining center performance, not just driven turret tools
12,000 RPM milling spindle enables high-speed finishing on aluminum and precision milling on steel and titanium
Direct-drive B-axis with 0.001-degree increment provides zero-backlash positioning for precise angular features
Optional sub-spindle enables complete done-in-one machining including back-end operations without unclamping
40-80 tool ATC provides the tool library depth needed for complex multitasking parts
Compact footprint relative to its capability makes the B200II accessible for shops stepping into multitasking

Limitations

130 mm Y-axis travel is narrower than some competitors, limiting off-center milling reach on larger-diameter workpieces
OSP control requires learning Okuma's multitasking programming approach, which differs from Fanuc and MAZATROL
Capital cost of $350,000-$500,000 requires consistent complex-part work to justify versus separate lathe and VMC
5,000 RPM main spindle speed is adequate but not exceptional for high-speed aluminum turning
Complex multitasking programs require advanced CAM software with dedicated Okuma post-processors

Best For

Aerospace job shops machining complex components requiring turning, milling, drilling, and angled features in a single setup Medical device manufacturers producing implants, instruments, and fittings with tight tolerances across turned and milled features Precision job shops consolidating multi-setup parts to reduce fixturing cost, lead time, and setup-induced positional errors Production shops running bar stock up to 65 mm where the sub-spindle option enables complete done-in-one parts Shops stepping into multitasking from separate lathes and VMCs, where the B200II's compact size and moderate price ease the transition Oil and gas component manufacturers producing valve stems, connectors, and fittings with complex geometries

Frequently Asked Questions

01 What does an Okuma MULTUS B200II cost?

A new MULTUS B200II typically runs $350,000-$500,000 depending on sub-spindle, milling spindle speed options, tool magazine capacity, and automation. This positions it as the entry point into Okuma's MULTUS multitasking lineup.

02 How does the MULTUS B200II compare to the Mazak Integrex i-200?

Both are 200-class multitasking machines with similar capacity. The Mazak uses MAZATROL SmoothAi with conversational programming, while Okuma uses OSP. Okuma's Thermo-Friendly Concept and Collision Avoidance are advantages. The Mazak typically offers 20,000 RPM milling spindle option versus 12,000 on the Okuma. The Integrex has a slightly larger Y-axis range.

03 What is the difference between the MULTUS B200II and B400II?

The B400II has a larger turning diameter (710 mm vs 630 mm), longer machining length (1,500 mm vs 750 mm), more powerful main spindle (30 kW vs 22 kW), and larger Y-axis travel (200 mm vs 130 mm). The B200II is for smaller parts where compact size and lower cost are advantages.

04 Can the MULTUS B200II do 5-axis machining?

The B200II provides 5-axis capability through X, Y, Z, B (milling spindle tilt), and C (main spindle rotation). It supports 5-axis positioning and can be configured for simultaneous 5-axis contouring. For complex aerospace surfaces, verify the specific control configuration with Okuma.

05 What CAM software supports the MULTUS B200II?

Major CAM systems including Mastercam, Esprit, GibbsCAM, Siemens NX, and CATIA support Okuma MULTUS post-processors. The complexity of multitasking programming typically requires CAM rather than manual G-code, especially for combined turning-milling-5-axis operations.
